Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a paper laminating tensioning mechanism. Background Art

[0002] Paper lamination is a post-printing process, which is to heat and pressurize a plastic film coated with adhesive and bond it to a paper printed matter to form a paper-plastic integrated product. The printed matter after lamination has a thin and transparent plastic film on the surface, which makes the surface smoother and brighter, not only improving the gloss and fastness of the printed matter, but also extending the service life of the printed matter. At the same time, the plastic film also plays a protective role in moisture-proof, waterproof, anti-fouling, wear-resistant, folding-resistant, and chemical corrosion-resistant. Therefore, the packaging printed matter after lamination can significantly improve the grade and added value of the commodity packaging. In order to ensure that the film and paper are closely attached during lamination, the film needs to be tensioned by a tensioning mechanism during lamination.

The utility model can automatically adjust the paper tension, save time, and thus improve the paper printing efficiency, the paper tension adjustment operation is relatively simple, suitable for use with papers of different paper materials and thicknesses, and has a wide range of applications.

[0004] However, in the above technical solution, when the film is tensioned, due to cost reasons, a tensioning roller is often used to tension the film, that is, the film is wound around the tensioning roller, and then the film is tensioned by adjusting the position of the tensioning roller. However, the current tensioning mechanism cannot clean itself during the tensioning process, which causes dust to accumulate on the surface of the tensioning roller during the tensioning process, resulting in bubbles formed between the film and the paper due to dust or incomplete attachment, which affects the film.

[0024] like Figure 3 and Figure 4 As shown, in another embodiment of the utility model, the tension roller 3 includes a tension roller body 301, and a first rotating disk 302 and a second rotating disk 303 are movably provided at both ends of the tension roller body 301, and a second gear 304 is fixedly provided on an outer wall of one side of the second rotating disk 303;

[0025] A rotating roller 305 and a dust shield 306 are provided between the first rotating disk 302 and the second rotating disk 303, a dust sticking paper roll 307 is provided on the rotating roller 305, and a brush 308 is provided between the rotating roller 305 and the dust shield 306. When paper lamination is required, the second gear 304 is first driven to rotate by the first gear 4, and the second gear 304 drives the second rotating disk 303 to rotate, so that the second rotating disk 303 rotates with the tensioning roller body 301 as the center, and the dust shield 306 and the rotating roller 305 are rotated to a suitable position according to actual needs, and then the tensioning roller body 301 is rotated, and then the dust sticking paper roll 307 is rotated. The tensioning roller body 301 that is tightly fitted with the paper roll 307 squeezes and drives the rotating roller 305 to rotate, so that the dust on the surface of the tensioning roller body 301 is adhered by the sticky paper roll 307, and the stubborn dust that cannot be adhered to the tensioning roller body 301 is cleaned by the brush 308, and the dust is blocked by the dust shield plate 306 to prevent the dust from escaping to various places.

[0026] The working principle of this paper laminating tensioning mechanism:

[0027] When in use, first move the positioning plug plate 10 into the inner cavity of the slide groove 8, and the spring 9 contracts. When the positioning plug plate 10 leaves the positioning slot 7, the fixation of the rotating column 6 can be released, and then the rotating column 6 is rotated. The rotating column 6 drives the first gear 4 to rotate, and the first gear 4 drives the second gear 304 to rotate. The second gear 304 drives the second rotating disk 303, so that the second rotating disk 303 rotates with the tensioning roller body 301 as the center. According to actual needs, the dust shield 306 and the rotating roller 305 are rotated to a suitable place, and then the positioning plug plate 10 is released, and the spring 9 rebounds, so that one end of the positioning plug plate 10 enters the positioning slot 7, thereby fixing the rotating column 6, thereby adjusting the position of the dust shield 306 and the rotating roller 305. The film is fixed, and then passed over the tensioning roller body 301, and the tensioning roller body 301 is used to tension the film. During the paper lamination process, the film drives the tensioning roller body 301 to rotate, and then the sticky paper roll 307 is used to adhere the dust on the surface of the tensioning roller body 301, and the brush 308 is used to clean the stubborn dust that cannot be adhered to the tensioning roller body 301, and the dust is blocked by the dust shield 306 to prevent the dust from escaping to various places. Finally, the dust in the dust shield 306 is adhered by the sticky paper roll 307, so that the surface of the tensioning roller body 301 is continuously cleaned during the lamination process to prevent the adhesion of dust to the surface of the tensioning roller body 301 and prevent the dust from affecting the lamination during the lamination process.
